Its habitat mainly consists of low altitude deciduous forests with thick vegetation and it will typically create its nest within trees, where they are practically indiscernible. totogo as more of a cryptic lineage and suggest treating it as an invalid taxon until further research is conducted. Whether these two populations should be considered distinct species has been debated in the scientific community, where some consider N. These two populations have been classified on the basis of being mitochondrially distinct, with slightly different breeding periods and a few specific morphological differences, such as wing chord length and tail length. Furthermore, the northern boobook species was also divided into the migratory subspecies N. scutulata based on specific vocal characters. japonica was classified as a species different from N. This group of owls with habitats spanning over East Asia, South-East Siberia, North Korea, Taiwan, Japan and the Philippines was recognized to have 11 phenotypically varying subspecies, before being divided into three distinct species in the early 2000s. scutulata, as one of the three species that make up the brown boobook complex along with the chocolate boobook, N. The Ninox japonica species was originally considered a conspecific with N. Select species within the genus are recognized for their reversed sexual dimorphism and a unique behavior called "prey holding" or "mantling". The Ninox genus, also called brown hawk owls, contains 36 species, with territories spread out over Australia and most of Asia. This has been hypothesized to be an adaptation due to the migratory nature of N. japonica, can be differentiated through the shorter wing chord (214-217mm) and the longer tail (118mm) of N. Aside from mitochondrial distinction, research has determined that subspecies of Ninox japonica, N. Its belly is almost completely white aside from rust-colored specks, which bear similarity to its sister species the brown boobook ( N. It has striking yellow gold eyes, a black beak and yellow talons. The neck, crown and face of this bird are slightly more greyish brown aside from a small white patch above the beak. Individuals of the species will have a brown back and wings with lighter brown horizontal streaks on the tail feathers. The northern boobook has a hawk-like appearance and its subspecies are practically indistinguishable. Current knowledge on the species shows no sexual dimorphism and an average weight of approximately 168g. Ninox japonica is a hawk owl species with a body length averaging between 29 and 33 cm and a wingspan of approximately 60 to 70 cm wide. There are no indications of significant decline in northern boobook populations and therefore its conservation status has been classified as least concern by the IUCN Red List. Despite being considered as the most common breeding owl in Japan, little research has been conducted on the species and subspecies and the taxonomic classification of N. ![]() The species currently includes two subspecies, the migrant Ninox japonica japonica and the non-migrant Ninox japonica totogo. The species was considered, until recently, a conspecific of Ninox scutulata or brown boobook, a species of similar distribution encompassing 11 subspecies. The northern boobook ( Ninox japonica) belongs to the family Strigidae (true owls) and is a raptorial owl endemic to eastern and southern countries of Asia.
